I own the Note 2 and iPhone 5, I like both as each phone has its own merits. I gave my wife the Note 2 since she has really bad eye sight. I always felt it was a grade better than the S3, if you don't need the larger screen I'm sure the S4 would be an awesome choice. Oh and I never use the stylus, the screen is so large the keyboard is AWESOME!

The S4 is very nice! Sleek. Very thin. Im a big guy though and love the feel of the Note 2. Always thought the size was crazy but i love it. Go to a store and look at them for yourself. See what you like better in hand. The Note is BOSS tho!!

I absolutely love my Note 2 one huge thing to consider is battery life. I don't know how it is on the GS4 but I can go a long day on LTE (LTE uses more battery than wifi). By long day I mean 3:30am to 10pm. Many people have reported simply incredible battery life from the note 2. I rarely use the stylus but it comes in handy from time to time. At this point you may wish to wait for the note 3. It will probably have at least some of the features that the GS4 has.
